Fir for the road.

One of the greatest obstacles to building up a bike is navigating the treacherous sea of industry standards. We simplify the bottom bracket odyssey with the Chris King ThreadFit Bottom Bracket Package for SRAM Road, which packages a ThreadFit 24 bottom bracket with a Conversion Kit #9. This adapts English threaded bottom bracket shells for use with SRAM-style, 24 to 22mm stepped crank spindles.
